Panoramic-view diving mask with self-sealing, non-glued removable watertight lens having contoured lips

Abstract

A panoramic-view diving mask with self-sealing, non-glued, removable watertight lenses. The lenses are self-sealed by an assembly process in which a layer of elastic gasket medium is applied or attached to either one or both beveled contacting edges of the frontal and side lenses, with the non-contacting edges having a lip so as to provide an enhanced seal between the lens and the frame. The lenses are assembled by pressing an assembly ring against the frontal lens and side lens simultaneously, forcing compression against the elastic gasket medium at the contacting edges of the two lenses and securing both lenses to the mask frame. The result is a watertight seal, achieved without adhesives, at the contacting edges of the front and side lenses. This process reduces storage space, packaging size and transporting costs during mass production. Also, this non-glued and removable self-sealing lens assembly allows individuals to easily replace a lens that is broken, scratched or corrected for near or far-sighted vision.

1. A panoramic-view diving mask comprising:
 a frame body having a frame groove; 
 at least one lens assembly comprising:
 at least one frontal lens with at least one contacting edge; 
 at least one side lens with at least one contacting edge; 
 a layer of elastic gasket medium capable of being applied or attached to at least one contacting edge of said frontal lens or said side lens; 
 said contacting edge of said frontal lens capable of mating with said contacting edge of said side lens; 
 said frontal lens having a lip along the non-contacting edges; 
 said side lens having a lip along the non-contacting edges; 
 
 said frontal lens and side lens fitted into said frame body such that said non-contacting edges contact with said frame groove and said contacting edge on said frontal lens mates with said contacting edge on said side lens; 
 at least one lens assembly ring located on at least one said frontal lens and at least one said side lens whereby said frame body simultaneously forcing said contacting edge of said frontal lens to press tightly against said contacting edge of said side lens in order to compress said layer of elastic gasket medium to create a water-tight seal. 
 
   
   
     2. A panoramic-view diving mask according to  claim 1 , wherein said lens assembly ring also comprising:
 at least one front partial lens ring having protruding tabs for engaging built-in slots on said frame body in order to securely station said frontal lens; 
 at least one side partial lens ring having protruding tabs for engaging built-in slots on said frame body in order to securely station said side lens. 
 
   
   
     3. A panoramic-view diving mask according to  claim 1 , wherein said means for applying or attaching said layer of elastic gasket medium to said contacting edges of said frontal lens and said side lens comprising:
 a layer of elastic gasket medium printed, laminated, coated or painted on said contacting edges of said frontal lens and said side lens; or 
 a layer of elastic gasket medium that can be inserted in between said contacting edges of said frontal lens and said side lens. 
 
   
   
     4. A panoramic-view diving mask according to  claim 3 , wherein said means for applying or attaching said layer of elastic gasket medium to said contacting edges of said frontal lens and said side lens further comprising:
 said layer of elastic gasket medium applied or attached to both contacting edges of said frontal lens and said side lens; or 
 said layer of elastic gasket medium applied or attached to said contacting edge of said frontal lens; or 
 said layer of elastic gasket medium applied or attached to said contacting edge of said side lens. 
 
   
   
     5. A panoramic-view diving mask according to  claim 1 , wherein said frame body comprises a molded-in frame groove. 
   
   
     6. A panoramic-view diving mask according to  claim 5 , wherein said frame groove can be assembled onto the body of the mask. 
   
   
     7. A panoramic-view diving mask according to  claim 1 , wherein said lens assembly further comprising:
 at least one left lens with a contacting edge and at least one right lens with a contacting edge; 
 a layer of elastic gasket medium applied to or attached to at least one said contacting edge of said left lens or said right lens; or 
 a layer of elastic gasket medium applied to or attached to both contacting edges of said left lens and said right lens; 
 said left lens mating with said right lens along the contacting edges.
